Birkenstock reported Q2 FY2026 EPS of €0.50 on 2026-05-28, missing the €0.5944 consensus by 15.9%.

Print-day reaction was +3.0% versus the prior close, a resilient move given the EPS miss. The overnight gap added another +1.5%, suggesting the market absorbed the shortfall and leaned constructive into the next session. Over the subsequent two trading days, however, the stock gave back ground, drifting –3.7% and erasing the post-earnings gains. Cumulative abnormal return of +0.23% versus SPY.US is effectively flat, placing this firmly in PEAD neutral territory; no drift signal is present through the holding window end of 2026-08-25.
